IMPROVEMENT IN MACHINES FOR CROSSING FIBRES IN FORMING- BATS FOR FELTING.

The Schedule referred to in these 'Lette'.xs Patent and making part of the same.

To all whom tt may concern Be it known that I, LYMAN ROBINSON, of Matkteawan, in the county of Dutchess, and State of New York, have' invented a new and improved Machine for Crossing the Fibre of Felts, Bats, \Vaddng, Ste.; and I do hereby declare that the following is a full, clear, and e.\"act description thereof, which will enable others skilled in the art to makeand use .the

same, reference being had to the accompanying draw ings, forming part of this specitication. The object of this invention is to provide a machine for crossing the brc of felted goods, whereby the same can be accomplished more expeditiously and uniformi y than by the means at present in use.

It consists of a machine having a broad platform, over which the fabric is passed back and forth from the carding-machine, whereon suitable rolling or laying-mechanism is placed, to receive a thin webbing from another carding-machine, delivered in a direction perpendicular to that in which the first-named fabric moves, and deliver it under the pressure f the layingrollers, moving back and forth, and laying it in a zigzag course as the fabric moves in one direction, the vacant angles being illed as the fabric is moved in the other direction. e Y Figure 1 represents a plan view ot` my improved ma.- chine.

Figure 2 represents a longitudinal elevation, taken on the line 11x of iig. 3.

Figure 3 represents an end elevation.

Similar letters of reference indicate corresponding part-s.

A represents the framing', whereon a broad table,

`B, is arranged, and suitable drawing or feeding-rollers,

Through the said rollers the webbing forming the base of the fabric to be made is fed from a cardingmachine on to the table B, over which it is drawn by other feeding or drawing-rollers, at the opposite end of the machine.

The said rollers C and O are operated by suitable gear-wheels, deriving motion from the main shaft D, and those at the other end maybe operated by any suitable means.

E and E represent a pair of'laying-rolleis, supported and attached in crotched arms, F, pivoted to the slides F', at G, and provided with the sliding weights, G', at their upper ends.

The, slides F are arranged to move back and forth on the ways F2, and are provided with toothed bars, F, to which a to-and fro movement is communicated, by pinions F4, gearing into-them, which are arranged on the vshaftF", arranged to rotate in either direction,

and which is changed from one direction tothe other as the said slides arrive at each side, and-communicate the necessary change tothe system of changewheels a, al, and a2, by means of' a lug, b, on one of the slides, striking the collars b1 and b2, on the rod b", connected to the slide b4, by a toggle-joint, which lnoves the clutch b5 alternately from wheel al to a2.

H represents arms, also pivoted, at their lower ends, t0 the slides F1, at Gr, and supporting at their upper ends, by a jointed connection, the arms II, which are in turn jointed, at their other ends, to the fixed supports H, secured, at their lower ends, to the frame,

at H3.

This system of jointed arms supports a system of guiding and drawing-rollers, which receive the webbing I from a direction perpendicular to the fabric I', on which it is to be laid,-and guides and delivers it to the laying-rollers E and E', as clearly represented in tiff. 3.

lK and K represent stops, to change the position of the layug-rollersas the direction of their motion is reversed; as, for instance, when they are moving toward the stop K, the roller E is the one required to lay the webbing I upon the other, and when moving in the other direction, it is necessary that the roller E' shodd be brought down into the operating-position, as is obvious.

lhis change is veffected by the lower ends of the crotched supports F, striking against the stops K and K simultaneously with the striking of the lugs b, on the collars b1 and b2 of rod bl, and throwing them over into the position opposite to that in which they stand at the time of striking, as will be readily understood by inspection of iig. 3.' The sliding weights G maintain them in their positions after bein g changed, against .the tension of the webbing, and furnish the necessary pressure of the rollers on the same.

By this arrangement, `the web I is vbeingvcontinnously laid back andforth on the web I', as it passes over the. table B, and will, consequently, be laid in an angular or zigzag course, leaving some of the web uncovered, and in order to lay it evenly on all part-s of the web I', the latter is passed back and forth over the said table, care being taken, at each time of revers- A ing its movement, to so adjust the relative movements ofthe two webs, that the parts of the web Ileft uncovered at one movement will be covered at the next.

The operation may thns'be continued until the fabric is laid up to any thickness', and the libres will be thoroughly crossed and interlaid, as will be well under# 4. The combination, with the slides F, carrying the laying-rollers, of the racks'l!13 and the system of changegearing, and the means for changing it, substantially as and for the purpose descvxibed.

The above specification of my invention signed by -me, this 4tbzday of September, 1868.

LYMAN ROBINSON.
